' 40 of'sheet material, the latter being bent inward at 40, 40, and provided with portions 42 for holding a strip 43 of felt or other material suitable for excluding currents ofy air.

At 44 isa tongue made of sheet material bent back upon itself and provided with portions 45 which are held against the edge of the bar 37 by aid of screws 4G. rl`he bar 37 1s provided with a hole 47 and mounted within this hole is a tube 48 which extends slightly from the sash. A bolt 49 is slidably mounted within the tube 48 and is disposed in alinement with a row of indentations .50 for receiving it. A spring 5l engages the bolt 4l) for the purpose of actuating it. Pins 52 are employed lor the purpose of holding the brackets 38 upon the bar 37.

The operation of our device is as follows: The operator grasps the bar 37 and moves it up or down, as desired. The bearings 39 slide in relation to the portions 32 of the bracket 38, the upper edge of the transparent screen v35 being raised or lowered. As the bar 37 is raised, the screen 35 is unwound from the roller 32 which turns for this purpose. The bar 37 being lowered, the roller 32 turns in the opposite direction so as to take up the slack of the screen 35. As this screen moves, the tongues 30, 3l which nt against it prevent the passage of air eurrents. The bar 37 ma be retained at any proximate level by ai of the indent-ations 50, as will be understood from Fig. 5. The bolt 49 merely slips into one of these indentations and prevents the bar 37 and consequently the screen 35 from further move- 'mentexcept at the will of the operator. The strip 43/ (see Fig. 4) being normally iixedv in relation to the column 40 and the tongue 44 projecting into'the loop formed b the stri 43, the admission of air throng the win ow is still further prevented.

Having thus described our invention, we claim as new and desire to secure by Letters atent:

1. In a window structure, the combination of a column provided with an opening, a strip of flexible material mounted upon said column and disposed partially within saidopening, a bar movable relatively to said column and provided with bearings engaging portions thereof, a tongue mounted upon said bar and engaging said strip, and a flexible member connected with said bar and adapted to be moved thereby as said bar is moved.

2. The combination of a column rovided with an opening, a bar disposed adjacent to said column and movable relatively to the same, a bracket mounted upon said bar and engaging portions of said column, a strip of flexible material connected with said column and bent into the opening thereof, a slidable member provided with portions engaging said column, and a tongue mounted upon said slidable member and engaging said strip of flexible material.

The combination of a pair of shields, tongues of iiexible material connected with said shields, a roller dis osed intermediate said shields, a 'screen oi. flexible material l wound partially upon said roller and extendingjoutwardly from said shields, said membeibeing engaged by said tongues, a bar f connected with said screen, and means for holding said bar at diii'erent levels.

v 4. In a window structure, the combination of a column provided with an opening, a strip of iiexible material disposed partially within said opening, a bar movable relatively to said column, a tongue mounted upon said bar and extending into said strip and into said opening, and a screen member connected with said bar and adapted to move therewith.

5. The combination of a column provided with an opening, and a strip of flexible material extending into said opening, means for securing said strip of flexible material in position upon said column, a bar disposed adjacent to said column and provided with a member extending into said opening and slidably engaging said strip of flexible material. p

6. The combination of a column of sheet material provided with portions bent away from each other so as to form an opening, a strip of flexible material extending partly into said opening, said strip of flexible material being connected with said portions of said column bent away from each other, a movable bar, and a member extending there! from into said opening and slidably engagin said strip of flexible material.

. Thecombination of a column of sheet ma,`

terial provided with an opening, and further provided with portions extending in opposite directions from said opening, said portions being bent back upon themselves, a strip of flexible material enga g said portions and held in position there y at the point where said portions are bent back upon themselves, said strip of flexible material extending into said opening, a bar disposed adjacent to said column of sheet material and movable relatively thereto, and bearings carried by said bar and engaging said portions of said sheet material bent back upon themselves.

8. The combination of a column provided with an opening, a bar movable relatively to said column and rovided with a member extending into said) opening for the purpose of restricting the flow of air through said ,opening, a screen of transparent material connected to said bar, and means for winding up a portion of said screen of transparent material.

9. In a window structure, the combination of a stationary member, a bar movable relatively thereto, a screen of flexible material connected with said bar, means for restricting the free HOW o f air around the edges of said screen., and a roller connected with said screen for partialy supporting the seme.

10. The combination of a Stationary framework, a bau movable in a predetermined glane relativey t0 `said framework, e. roller isposed` adjacent to said frumewol'k, and a -iexble screen Wound partially upon seid roller and connected With Said ber for the purpose-0f enabling movements of said bmjvided with a member extending n'o said opening7 :L screen of transparent flexible 11m.- -eral eenneciec with Seid be' :md 'with said fl'mnewmk, Said screen. having im edge extending into said opening, :md el` relier having weund, libel-@einen d pefftun of seid Screen oppomte said bm'.
